Abstract
The utility model provides a pipe pile steel reinforcement cage with a steel strand consisting of a prestressed reinforcing bar and stirrups surrounding the prestressed reinforcing bar, wherein two ends of the prestressed reinforcing bar are nested in the counter hole of the inner surface of the tip plates on two sides respectively, the steel strands installed close to the prestressed reinforcing bar are connected with the tip plates on two sides. The steel reinforcement cage combined by the steel strands and the prestressed reinforcing bar participates with the prestress tension after the molding of the pipe pile and concrete, the pipe pile is obtained through centrifugal molding and maintenance, changing the shortcomings including that the existing pipe pile has a bad bend resistance and poor ductility, and is easy to be brittle, besides, the pipe pile cracks rapidly, the pulled reinforcing bar yields, tightens and even becomes fractured in a fast rapid, and ultimate bending moment has little difference with cracking moment. According to the pipe pile steel cage with a steel strand, the ductility and horizontal shear resistance force of the pipe pile have been enhanced, besides, the machining technology is simple, and the operation is convenient and can be wildly applied.
Description
Technical field
The utility model belongs to the reinforcing cage field that pile tube is made, and especially relates to a kind of pipe pile reinforcing bar cage of being furnished with steel strand.
Background technology
In planting a process as to run into geology be deep foundation ditch, entering bearing stratum is that hard embedding petrosa divides, and when the off plumb situation was arranged, hard formation embedding petrosa divided with deep foundation ditch part pile tube and just easily produces transverse fissure, and the top pile body will form lateral displacement, the easily skew of stake position.During interface that the interface that Soft Soil Layer deep foundation ditch pile tube forms with it when entering into the hard soil layer, soft or hard have a common boundary, just run into the pile body position and also easily produce the transverse horizontal shearing, when exceeding the limit of horizontal bearing, the same easily fracture of pile tube etc.Pile driving pressure sudden change during pile sinking, because soil compaction effect, earth heaving, pore water is not subdued again, forms tensile stress, and when tensile stress during greater than the stress of stake self, the pile body position just easily produces broken pile.Seismic wave runs into Soft Soil Layer and forms side direction horizontal shearing formation displacement destruction, the rigidity of pile tube self.Be the degeneration of concrete strength and rod iron intensity, can resist the impact of formed external shearing under the geological process.In the piling of the place of soft or hard sudden change, in case when pile tube passed through hard interbedded layer, this moment, the pile body bounce-back was severe especially, when upwards the hammering of the frequency of bounce-back and tup is inconsistent with the drop of stake therebetween (heavy hammer and low strike), in this case, rigidly carry out hammering, the just easily fracture of pile body this moment.Solve the pile tube easy fracture and become one of vital task.
